BTCRecover.py and Multi GPU issue.

Hello,

I have a btc250 motherboard with 6 3080's and 2 3060 Ti's plus the embeded video card. No matter what I do I am not able to get btcrecover.py to use more than one GPU at a time. btcrecover sees all 8 of the video cards but it will not use them when trying to brute force a password seed. I am using ubuntu 24 LTS and I have installed everything from scratch following the guide on the btcrecover document site. Any guidance on how to resolve this issue would be greatly appreciated.
